We found a pair of chitons, one rather plain the other a crazy pink:
We also found a polychaete worm. S/he had an impressive little tuft of antennae on the head.
Being in a bit of an interested-in-shellfish phase right now I took a pic of this one happily hunkered down surrounded by coraline and red algae:
It promptly sprouted legs, antennae and eyes, and marched off, a bit of 'no pictures!' in its hermit crabby manner.
An upended rock revealed an anemone amid a colony of Pomatoceras worms with some green seaweed (Ulva lactuca) trying to get established.
The youngest field assistant wanted to poke his finger into the anemone's mouth. The rock was replaced, the anemone unpoked after a quick lesson about nematocysts.
